y = -6x
y = -4x + 4

Answers

Answer 1

Answer:

x=-2 y =12

Step-by-step explanation:

Eliminate the equal sides of each equation and combine.

−6x=−4x+4

Solve

−6x=−4x+4

x=−2

y= 12

The solution to the system is the complete set of ordered pairs that are valid solutions.

(−2,12)

The result can be shown in multiple forms.

A projector displays an image on a wall. The area (in square feet) of the projection is represented by x^2-8x+15
a. write a binomial that represents the height of the projection
b. find the perimeter of the projection when the height of the wall is 8 feet​

Answers

Answer:

a. (x - 5) ftb. 16 ft

Step-by-step explanation:

The area given:

x² - 8x + 15

a. The height is the factor of the area:

x² - 8x + 15 = x² - 3x - 5x + 15 = x(x - 3) - 5(x - 3) = (x - 3)(x - 5)

The width is x - 3, so the height is x - 5

b. The perimeter formula:

P = 2(x - 3 + x - 5) = 2(2x - 8) = 4x - 16

The height of the wall is 8 ft:

x = 8

The perimeter is:

P = 4*8 - 16 = 32 - 16 = 16 ft

joe finished his english assigments in 1/3 hours. Then he completed his chemistry assigment in 1/8 hours. What is the total amount of time joe spent doing these two assigments as a fraction in simplist form./ Aleks

Answers

To answer, we need to add the two fractions. However, to add them, they need to have a common denominator (the number on bottom). One easy way to do this is to multiply both so they are the same number. Use the opposite number! Then, you can add the numbers straight across. You will most likely need to simplify. If you have any further questions, let me know!
The lowest common denominator would be 24 for these 2 fractions...so change 1/3 into 8/24, and 1/8 into 3/24. Add them together and you see that it took him 11/24 hours to do both assignments. That won’t simplify any, so 11/24 should be your answer.

There are 250 bricks used to build a wall that is 20 feet high how many bricks will be used to build a wall is 40 feet high?

Answers

Answer:

500 bricks.

Step-by-step explanation:

There are 250 bricks used to build a wall that is 20 feet high how many bricks will be used to build a wall is 40 feet high?

To solve e the above question, we have:

20 feet high = 250 bricks

40 feet high = x bricks

Cross Multiply

20 feet × x bricks = 40 feet × 250 bricks

x bricks = 40 feet × 250 bricks/20 feet

x bricks = 500 bricks

Therefore, 500 bricks will be used to build a wall is 40 feet high.

what are the like terms in the expression 8+x^2-4x^3+5x+2x^2?​

Answers

Answer:

B. x^2x2 and 2x^22x2

Step-by-step explanation:

The expression given is:

8+ x^2 - 4x^3 + 5x+ 2x^28+x2−4x3+5x+2x2

Like terms are terms in which their variables and the power of the variables (exponents) are the same.

While it is not necessary that the coefficient of the variables are the same, the power of the variables must be the same.

In that case, the like terms in the expression given are x^2x2 and 2x^22x2 .

Note: The question says 8+ x^2 - 4x^3 + 5x+ 2x^28+x2−4x3+5x+2x2 but the option has -4x^2−4x2 .

In case its actually -4x^2−4x2 instead of -4x^3−4x3 , then,

 -4x^2−4x2 is also a like term and the answer will be D.

What is the output of the function when the input is 10? On the graph plot this point and label its coordinates

Answers

Answer:

Output value = 20

Step-by-step explanation:

Graph of any function is made up of two values → Values on x axis and Values along y axis.

x values represent the input values and y values represents the output values.

For every x value there is a y value because of which the data set is called to a function.

In other words, a function can't have two output values for a single input value.

If the input value of function is = 10

Then for x = 10, out value (along y axis) will be = 20

Therefore, Output value of the given function is 20.

TVs are usually measured as a diagonal distance across the screen for screen measures 15.1 inches in height and 19 inches diagonally what is the width of the screen round to the nearest 10

Answers

Answer:

11.53 inches

Step-by-step explanation:

Given data

Diagonal = 19 inches

Height=  15.1 inches

Let us apply the Pythagoras theorem

D^2= H^2+W^2

substitute

19^2= 15.1^2+W^2

361=228.01+W^2

361-228.01=W^2

132.99= W^2

W=√132.99

W=11.53 inches

Hence the width is 11.53 inches

Answers

Answer: 2²/₃ pounds

Step-by-step explanation:

The weights of each fruit salad will therefore be:

= Pounds of fruit/ Number of fruit salads

= 8 / 3

= 2²/₃ pounds

(1a) Do 4x and 15 + x have the same value when x is 5? How do you know?

Answers

Answer:

Yes, both have the same value ( 20) when x = 5.

Step-by-step explanation:

We have two functions:

y = 15 + x

y = 4*x

We want to see if these functions have the same value when x = 5.

Then we just need to replace x by 5 in both equations, and see if the values of y are the same

first function:

y = 15 + 5 = 20

second function:

y = 4*5 = 20

So yes, both functions are equal to 20 when x = 5.

Answer:

Yes.

Step-by-step explanation:

4(5)=20

15+5=20

The captains of the soccer team describe ordering identical T-shirts for the team. Bindi says the total cost is $192. Gina says the cost is 8t, where t is the number of T-Shirts. Which person tells how much each T-shirt costs? How do you know?

Answers

Answer:

Both of them.

Step-by-step explanation:

Gina says the cost is 8t, which means you can easily find out the cost of each t-shirt if you know the the total cost too. Bindi says the total cost was 192, which is completely useless on its own, but paired with Gina's info, you can get the answer. Divide 192 by 8, and you get the cost of each t-shirt.

Answer:

T=4

l=11.60

T is for time,and time given is 4.

so t=4 years

and Interest given is 11.60 bucks

so I=11.60

keep in mind that PRINCIPAL IS NEVER A PERFENTAGE!

RATE IS ALWAYS A PERCENTAGE!

Here, principal is 100 bucks and rate is 2.9%

Point (7,12) is rotated 1260° counterclockwise about the origin. What is the X-coordinate of the point after this rotation?

Answers

Given:

Point (7,12) is rotated 1260° counterclockwise about the origin.

To find:

The  x-coordinate of the point after this rotation.

Solution:

If a point is rotated 360 degrees then its coordinates remains unchanged.

If a point is rotated 180 counterclockwise about the origin degrees, then

[tex](x,y)\to (-x,-y)[/tex]

We know that,

[tex]1260^\circ=1080^\circ+180^\circ[/tex]

[tex]1260^\circ=3\times 360^\circ+180^\circ[/tex]

After [tex]3\times 360^\circ[/tex] rotation the coordinates of points remains same, i.e., (7,12). So, after that (7,12) is rotated 180° counterclockwise about the origin.

[tex](7,12)\to (-7,-12)[/tex]

The point (7,12) becomes (-7,-12) after rotation of  1260° counterclockwise about the origin.

Therefore, the x-coordinate of the required point is -7.

Step-by-step explanation:

start of the numberline .7                                       .750

end of the numberline .8 wanna see how? look. .800

(zeros after the decimal number dont matter but im showing you that the eight is bigger) I'm trying to show you that .8 is bigger. Obviously the .8 is bigger.
